Description

Soap Compositions Containing Gold-Coated Yellow Pigments

The present invention relates to an inorganic powder coated with yellow iron oxide or a yellow pigment coated with gold on a yellow iron oxide surface. More particularly, the surface activity of the inorganic powder is lost by coating gold on the powder, and thus the activity is lost. The present invention relates to a soap composition containing a gold-coated yellow pigment capable of obtaining the effect of stabilizing the raw material contained in the soap by containing the pigment.

Conventionally, soaps containing inorganic powders contain various fragrances and drugs in addition to the inorganic powders. In this case, the decomposition of the perfumes or the drug is promoted by the catalytic activity of the inorganic powders, and as a result, deodorization and discoloration result in product value. There was a problem degrading. For example, linarol or linarylacetate is easily decomposed by the acidic inorganic powders contained therein and loses its original fragrance, and in the case of soaps containing basic inorganic powders, isomerization of α-pinene or There is a problem that the disproportionation of benzaldehyde is promoted and the original purpose is lost.

In addition, in the soap containing gold in the prior art, gold is contained in the form of gold foil, it has a problem in that the dispersibility is poorly dispersed, it is difficult to mix with other compositions, poor appearance and lower the value of the product.

Therefore, the inventors of the present invention, while researching a method for reducing the catalytic activity of the inorganic powder in the soap containing the inorganic powder in the ordinary soap base, thereby achieving stabilization of the other components contained in the soap, inorganic powder It has been found that the catalyst activity can be remarkably suppressed by coating with gold, thus completing the present invention.

Accordingly, an object of the present invention is to provide a soap composition that can significantly inhibit the catalytic activity of the inorganic powder, further promote skin metabolism, maintain the health of the skin, and give a visual pleasure by the golden color .

The object of the present invention as described above can be achieved by containing an inorganic powder coated with yellow iron oxide or a yellow pigment coated with yellow iron oxide with gold.

Soap bases used in the present invention are soap bases commonly used in the art as 65 to 85% by weight of sodium tallowate and 15 to 35% by weight of sodium cocoate. Composed of soaps [see; Soap Technology For The 1990's.

The gold-coated yellow pigment according to the present invention is an inorganic powder coated with yellow iron oxide, for example, mica, silica, titanium dioxide, zinc oxide, zirconium oxide, talc, kaolin, iron oxide, alumina and the like, yellow iron oxide Coated; Or a single yellow iron oxide coated with gold. It is preferable that the inorganic powder or yellow iron oxide coated with such yellow iron oxide have an average particle diameter of 0.01 to 20 µm.

As a method of coating gold with the said yellow iron oxide-coated inorganic powder or yellow iron oxide, it is performed by the collection method which suspends and disperse | distributes the said powder in dilution liquid of liquid, and sinters at 450-600 degreeC. The hot sintered molten metal is converted into pure gold and coated on the powder to become a gold pigment of the gold system.

The collection used above is a mixture of gold, turpentine oil, and sulfur, which is diluted to a concentration of 1 to 50% (w / w) in a diluent.

The soap composition of the present invention is characterized in that it contains 0.01 to 10% by weight of the yellow pigment obtained by coating the gold by the above method with respect to the total weight of the soap composition.

Hereinafter, the present invention will be described with reference to embodiments of the present invention for a more specific understanding of the present invention.
